Abstract: 1,051,170. Electrode materials and processing. SYLVANIA ELECTRIC PRODUCTS Inc. March 31, 1964 [May 2, 1963], No. 13222/84. Heading HID. A process of fabricating an arc tube for a high-pressure discharge lamp comprises sealing a non-thoriated electrode into each end of the tube, subsequently introducing arc-forming ingredients including thorium into the interior of the tube through an exhaust tube, and forming an arc in the tube to cause thorium to be deposited on the electrodes. As shown, the tube 16 has tungsten electrodes with shanks 1, 4 and helical windings 2, 3 in the ends 12, 14 of the tube. Shanks 1, 4 are attached to molybdenum foils 5. 9 to which the leads 6, 11 are joined. The non- thoriated electrodes are positioned in the end portions of the tube and sealed by heating the glass and when soft making a press seal. A stream of inert gas is directed into the envelope during heating to provide an inert blanket on all metal parts to prevent oxidation. The tube is then purified by adding a gas in which an arc can strike and then striking an arc to drive occluded gases and residual carbon into the tube from whence it is removed by placing the tube under a vacuum and then filling the envelope with a purge gas. This may be repeated. A vacuum is then drawn and thorium, mercury and iodine are added through the exhaust tube together with a conventional filler gas. The exhaust tube is then sealed off and an arc struck which causes the thorium to react with the iodine to form thorium iodide which migrates back to the electrode where it dissociates and the thorium plates out and gradually forms a ball tip. Gases, quantities, times and temperatures are specified. Cadmium and thallium may be added for changing the colour and sodium for changing the shape of the arc.

Electrostatic charging and heating of objects, particularly flat objects overlaid with synthetic enamels. during polishing thereof is eliminated by treating the surfaces of the object to be polished with cooling air produced from a blower containing or in combination with a finely divided fluid containing an antistatic. A workpiece 8 is fed by a conveyer belt 3 under polishing rollers 5. Air from a blower 12 entrains liquid from a container 20. The container 20 is fed with liquid from a supply vessel 29, the container and vessel having liquid level indicators 31, 30. The air with atomized liquid passes to a pipe 18 and thence to nozzles 34, 35. The nozzle openings are maintained at the desired spacing from the surface of the workpiece by pivotally adjustable arms 38 carrying rollers 40 contacting the workpiece surface. The blower 12 and pipe 18 may be duplicated on the other side of the machine. A casing 42 has ventilation shafts 43. A thermometer 44 is provided for checking the temperature of the blowing air. The liquid is preferably 90% water and 10% anti-static.
